My grandfather believed this, my father believed this, and therefore, i believe this! " what is the fallacy in this statement? a) it posits an unquestioning faith in nature. b) it posits an unquestioning faith in the wisdom of one's forebears. c) it implies an unbroken family line where it doesn't necessarily exist. d) it sends the message that grandfathers, fathers, and sons always make the same mistakes.

B) It posits an unquestioning faith in the wisdom of one's forebears.

Explanation:

An argument, a belief, an idea etc. should only be assessed based on its logical values.

In simple turns, disagreeing with someone just because you don't think much of him, or, contrary, accepting someone's argument just because he is dear to you, or famous, or doing something just because everybody else does it, are all examples of some of the logical fallacies.

Only if conclusion arises from valid reasoning and true premises we can avoid making fallacies.

B) It posits an unquestioning faith in the wisdom of one's forebears.

Explanation:

The fallacy in above statement is that it posits an unquestioning faith in the wisdom of one's forebears.

This means that a person does not think of questioning the wisdom of their fore fathers, rather they trust them blindly. There could be a possibility of them being incorrect but this thought does not cross their minds.

Thanks for asking.
